Opis:: This study investigated the deterrence effect of the police patrol on the road safety in China and the research purpose was achieved by questionnaire survey and data regression. Firstly, a questionnaire survey was carried out to investigate the drivers’ illegal behaviours and attitudes to safety measures, such as police patrol, surveillance cameras and warning signs, and 137 drivers participated in the survey; the statistical results showed that 45.3%, 4.4% and 16.8% of the respondents had the experience of speeding, driving under influencing of alcohol and fatigued driving respectively; all of the participants believed that traffic police patrol would change their dangerous driving behaviours and police patrol is most effective among three road safety measures based on the investigations. Secondly, data about police patrol frequency and road crash rate on the road segment was collected from the local Transportation Administration Bureau and the regression analysis based on the data was conducted to investigate the direct effect of traffic police patrol on road safety improvement. The results indicated that increasing the frequency of police patrol has an obvious positive effect on improving the road safety and it is consistent with the results from self-reported questionnaire survey.

Opis:: In previous works the research team submitted [1-5] a series of numerical analysis of the car - road barrier dynamical system, directed to the elaboration of the numerical model methodology of an impact problem with the use of the chosen CAE programs. In this article there are presented the results of works on numerical implementation of crash tests of a car with the modified road barrier. The results are presented on the example of the Suzuki Swift car impact into the road barrier, which is equipped with the additional protective panel. The panel consists of the foamed aluminium plate whose fastening to the belt of the W-beam guardrail and a shield presented itself a thin-walled open profile made from the polyester-glass laminate. The whole construction was connected with the W-beam guardrail by riveting. The Geo Metro (Suzuki Swift) car, commonly available model from National Crash Analysis Centre (NCAC), was used for numerical analysis of the car-barrier system. Numerical analysis was carried out with the use of LS-Dyna system. The comparison of the time courses of acceleration, acting on the vehicle centre of gravity and the ways of the barrier and car deformation, achieved by the experimental and simulation ways, took place. The good qualitative and quantitative conformities in accelerations w archieved.

Opis:: A vehicle hitting a traffic barrier creates a major threat to traffic safety as a result of displacement of components of the barrier by the forces transferred from the vehicle. We built a theoretical model of the dynamics of such processes and behaviour of concrete barriers set on various types of surfaces. We calculated the displacement as a function of vehicle impact energy and barrier base. We completed analytical approximation for our calculations and we referred the theoretical results to experimental test results. This validated our model of barrier and vehicle movement dynamics as fully qualified for use in the planning of safer barriers and evaluation of barrier effect on traffic. Basing on our calculations, we determined that a second-order polynomial can be used for describing the lateral displacement of a barrier placed on various types of surfaces for a wide range of impact energies (actually, from O to 120 kJ). The courses of the approximating function represent an efficient model for determining the maximum lateral displacement of a concrete barrier on impact of a B or C segment vehicle.

Opis:: In this article experimental results of a car impact into a modified road barrier are presented. For crash tests a modified protection barrier SP-04, composed of guide poles, type B, and bridge posts IPE140, was chosen. The road barrier modification lies in using additional panels absorbing the impact energy. The protective panels, subjected to examination, consisted of a metal or a composite (laminate, glass-polyester) shield in which the f o amed aluminium or polyurethane foam was a filling. The Suzuki Swift car s were prepared for the crash tests. Tests were carried out at the Automotive Industry Institute (PIMOT) in Warsaw, with the use o f a test sample of the road barrier. For the safety sake the car's speed during the experimental examinations was limited to 50 km/h. Moreover, the vehicle hits perpendicularly in a properly modified road barrier's sector. During the test a registration of acceleration was carried out by the acceleration sensors placed in the car (among others in the centre of gravity and over the rear axle of a car). A crash test course of the system C-G was registered with the use of two cameras for fast shooting (Fantom v12). An image was recorded with the resolution of 1280 x 800 pixels and with frequency of 1000 shots per second. The shot exposure time equalled to 250 microseconds.

Opis:: High accident index in Poland, including one of the highest death rates in EU, forces undertaking the intense works in order to improve traffic safety. Published road accident statistics indicate that the most dangerous accidents include a vehicle collision with a tree, post or other road object. The road safety barriers make the road infrastructure elements that can signiflcantly protect against that type of accidents. The work presents basie tasks and requirements imposed on the barriers. Problems related to a proper selection of the barriers have been also highlighted. The tools facilitating the barrier design include numerical modelling. The modelling has been done by means of the LS-DYNA software, using the finite element method. A general structure and a developed barrier model as well as vehicle model have been presented. The conditions of the numerical tests have been also specifled. The work presents the results of influence of car impact angle with a rigid safety barrier. Presented results refer to a car o f mas s of 900 kg, making a bas is for the tests of the limiting systems for several limiting levels: including normal limit N2 (according to EN 1317-2). Compared to standard requirements, the scope of numerical tests has been extended by other car impact angle values. The work presents vehicle trajectories and deformations of their bodies. It also includes examples of velocities and acceleration courses and acceleration severity indexes (ASI) calculated on their basis. Obtained results indicate that the barrier location angle has a high influence on the safety level ofthe car passengers as well as on the car motion trajectory after collision

Opis:: The work presents the traffic safety issue related to a use of the road protective barriers. It describes a purpose and tasks that should be fulfilled by the safety system. Conditions of crash tests and their evaluation according to the requirements of the existing standard documents are also presented. The purpose of the work was to evaluate the influence of applied barrier type on the car collision process. A barrier composed of the segments that can move on the ground due to the impact force and a barrier fixed to the road surface were assumed for the model tests. The modelling was carried out by means of the LS-DYNA sofrware, using the finite element method. The tests were performed for two types of cars, mass of 900 kg and 1500 kg. The work includes the numerical test results, deformations of car bodies and barrier displacement. Examples of velocities and acceleration courses of selected vehicle elements and the ASI index, calculated on their basis, used for evaluation of the passenger danger level were also presented. Obtained results indicate a significant influence of the barrier installation method (joint with the road) on the collision process course and dynamic loads affecting the car passengers. They also indicate directions of safety improvement.

Opis:: The paper evaluates the effectiveness of the innovative road safety system equipped with prototype component segments composed of a body made of a plastic filled with reinforced concrete. Main advantages of the new safety barrier include increased resistance to corrosion as well as easy transport and assembly directly on a road section being secured. Model tests were performed on a car of 900 kg weight allowing for carrying out the TB11 tests according to the EN 1317-2 standard. LS-DYNA software was applied for modelling, using the finite element method. The work presents the numerical test results, trajectory of vehicle movement after collision as well as the concrete barrier displacement. It also includes examples of stress in steel bars and joint coupling. Detailed assessing of simulation test results were made on the basis of ASI, THIV and PHD index. They were calculated on the basis of velocity and acceleration courses of selected car bodywork points. Numerical test results confirm the fact that this system meets the normative requirements. They allow for qualifying that system for B impact severity level and W4 working width. The results presented in the paper make the initial stage of the study and further calculations will be oriented towards a possibility of meeting the requirements for higher restraint levels.

Opis:: The work describes methodology of selection of a prototype articulated joint used to connect the segments of the concrete protection barrier. The barrier and the joint have been made according to the original project of the authors of this paper. Dimensions of the component elements of the joint were defined on the basis of numerical calculations in LS-DYNA system, using finite element method. They also allowed to identify places sensible to damage. Based on the project, the experimental tests have been performed for the joint strength to stretching. The tests performed on the resistance machine showed improper technology and poor quality of welds joining individual elements, particularly the bolt with connecting steel. Results of these tests made the basis for introducing the changes to the project. Repeated tests confirmed their rightness. The final evaluation of quality and usefulness of the prototype articulated joint in the connections of movable protection barrier were defined during the crash tests on the test track of the Certified Research Laboratory of the Research Institute for Roads and Bridges. The crash tests were performed for selected collision criteria (TB11 and TB32), normal restrain level (N2), using three passengers cars. Applied concrete barrier test procedures are in accordance with the requirements of national standards, that make the equivalents of the European standards.

Opis:: The work considers changes occurred in the features of the supporting structure in three categories of cars, namely: with the self-supporting body, framed body an intermediate structures between these two solutions. The area of analysis includes the length of deformation (crush) of the front al part of the car after collision with a rigid obstacle (barrier). The range of deformation is a significant factor of the passive car safety and indicates the efficiency of fulfilling the protective function for the passengers. The work shows absolute and relative (percentage and unit) variations of the car deformation, depending on the year of manufacture, including the period of 1980 - 2010. Marked trend lines indicated general nature of the deformation range variations together with the improvement of the car supporting system structures. The course of the trend line has been calculated on the basis of average deformation length values, calculated in defined periods of vehicle manufacture. Selected sections of time result from the division of the period of analysis 1980 - 2010 into six parts. The analysis of the deformation length of the frontal part of passenger cars, SUVs and pickups has been combined with simultaneous evaluation of total car length variations and their weight values. The car weight directly affects the kinetic energy of the impact so it has a significant influence on the range of deformation of the car front during collision with an obstacle.

Opis:: Road accidents with participation of the children are of particular nature. According to surveys, the older children at the age of 8-12 years are often transported in cars in a wrong way. They are usually fastened with seat belts designed for adult passengers. In order to make the seat belts safe for a child, they should be used together with a booster cushion or a high back booster seat. This paper presents the test results and analysis of dynamic loads affecting a child in the back seat of a passenger car during a frontal collision. The car body was accelerated to a speed of about 48 km/h and then it was suddenly stopped in a time of about 100 ms. The analysis was carried out on the basis of results of experimental tests performed at the collision station in the Automotive Industry Institute in Warsaw. The attention was paid to the influence of protection device type on the P10 dummy, representing a child at the age of about 10 years. Three child protection options during a collision were considered: the dummy was sitting directly in a car seat, on a booster cushion and on a seat. The dummy was fastened with standard seat belts. Evaluation of the protection device influence on the dummy loads was given in association with the operation of the seat belts. During evaluation, the indexes of biomechanical resistance of a human body to the impact load effects were used. They made the basis for the evaluation of the child injury severity risk.

Opis:: Human body motion during a road accident usually results from the effect of forces of inertia. The analysis of that motion, particularly displacements towards the vehicle interior have significant practical aspect as it facilitates conclusions concerning the mechanisms of danger and injury formation. At the same time, the analysis provides direct indications regarding the improvement of passive safety equipment. The paper presents the time-space diagrams of motion of dummy’s head, neck, torso and hips – the driver of a frame chassis vehicle, identified on the basis of results of the measurements registered in frontal barrier impact and the frame-by-frame analysis of videos recorded during the course of experiment. Courses of these diagrams were associated with acceleration measurement results and forces affecting the parts of the dummy. The experiment showed the complex nature of the influence on the dummy caused by the forces of inertia after a collision of the vehicle with an barrier, vehicle body motion against the frame, reactions in the safety belts, friction on a seat and contact reaction of the vehicle interior equipment. At the same time, it presented the possibilities of indicating the courses of speed variations and dummy displacement as well as significant limitations of calculation possibilities that result from a fact that the process of the impact on the vehicle interior elements is hard to describe.

Opis:: The analysis carried out by the authors indicates high threat to the rear seat passengers in passenger cars during a road accident. Vehicle designers indicate potential threats for passengers when they take a position in a car which is unexpected by a manufacturer of passive protection systems. Based on that, the tests were prepared in order to consider several different positions of a rear seat passenger. In particular, attention was paid to a threat to passengers when they take a position unexpected by a manufacturer of the passive protection systems in a car. Indicating and justifying a need to adjust the operation of the individual protection means to a passenger anatomy and current passenger position in a car in order to optimize his protection makes an important aim of these tests. This paper presents the results of the tests performed with a Hybrid III dummy, size M50, placed in three different positions in the back seat of a car. During each test, a series of physical values were measured and the motion of a dummy against the car body and the car interior components were filmed. The effects resulting from a change of a passenger’s position, observed on the courses of dynamic loads occurring during an accident, were analysed. Despite of small changes to a passenger’s position, their significant influence on the dummy movement during a frontal collision of a car and an obstacle was observed.
